XPERTMATIC Premium 200W/300W Aquarium Heater for 15–26 Gal Tanks, 65–93°F Adjustable, Submersible Fish Tank Heater with External Probe & PID Control, Auto Shut-Off, Quartz Glass, Fresh & Saltwater Safe

Product Description Enhance your aquarium heating experience with a heater designed for safety, precision, and durability — far surpassing a basic heater that merely turns on and off. The external temperature probe quickly senses when water drops below safe levels and automatically cuts the power, eliminating the risk of dry burning — a serious issue with conventional heaters, such as many basic submersible models, that rely on internal sensors. Featuring PID intelligent temperature control, not simple thermostat cycling, this heater maintains target temperatures more steadily and efficiently — ideal for breeding setups, sensitive fish, shrimp, and aquascapes. The fully corrosion-resistant quartz glass tube ensures long-lasting performance in freshwater and saltwater environments alike. Whether you’re running a planted freshwater tank or a marine reef display, this heater delivers reliable, safe warmth with the confidence that typical heaters can’t match. Intelligent PID Temperature Control Advanced PID control adjusts heating power in real time, keeping water temperature stable. Reduces fluctuations and helps protect fish, shrimp, and plants from stress Smart PID Variable Heating Indicator Smart PID variable heating adjusts power automatically. Red light shows active heating, green light indicates target reached. Safe and reliable for both fish tanks and turtle tanks
